Study finds Earth’s magnetic field ‘simpler than we thought’

Scientists have identified patterns in the Earth's magnetic field that evolve on the order of 1,000 years, providing new insight into how the field...

Geophysicist Helps Develop High-Res Map of Earth’s Magnetic Field

A University of Kentucky geophysicist is helping an international team of scientists reveal dramatic new information about the Earth's magnetic field. Two years ago, Dhananjay...

Upper part of Earth’s magnetic field reveals details of a dramatic...

Satellites have been mapping the upper part of the Earth magnetic field by collecting data for three years and found some amazing features about...

‘Quartz’ crystals at Earth’s core power its magnetic field

The Earth's core consists mostly of a huge ball of liquid metal lying at 3000 km beneath its surface, surrounded by a mantle of...

Ancient jars found in Judea reveal Earth’s magnetic field is fluctuating,...

Albert Einstein considered the origin of Earth's magnetic field one of the five most important unsolved problems in physics. The weakening of the geomagnetic...

Earth’s magnetic fields could track ocean heat

As Earth warms, much of the extra heat is stored in the planet's ocean—but monitoring the magnitude of that heat content is a difficult...

Marine sediments record variations in the Earth’s magnetic field

Past variations in the strength of the Earth's magnetic field are reflected by the production of isotopes in the atmosphere. Researchers from the CNRS,...

Uncovering Yellowstone’s subsurface mysteries

A new study providing an unprecedented regional view of the earth's crust beneath Yellowstone National Park will begin with a helicopter electromagnetic and magnetic...

Magnetic oceans and electric Earth

Oceans might not be thought of as magnetic, but they make a tiny contribution to our planet's protective magnetic shield. Remarkably, ESA's Swarm satellites...

Magnetic attraction helps explain the motion under the ocean

The EU GEOPLATE project uses magnetic sensing techniques to expand our understanding of the earth's tectonic past, while also offering tools to help locate...

Using magnetic data: Researcher uncovers 340 million year-old oceanic crust in...

A researcher at Ben-Gurion University of the Negev (BGU) has identified that the eastern Mediterranean Sea contains the world's oldest oceanic crust still in...

What did Earth’s ancient magnetic field look like?

New work from Carnegie's Peter Driscoll suggests Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather...

Ironing out the mystery of Earth’s magnetic field

The earth's magnetic field has been existing for at least 3.4 billion years thanks to the low heat conduction capability of iron in the...

Just what sustains Earth’s magnetic field anyway?

Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of...

Minerals reveal record of magnetic fields

Fresh discoveries about common minerals are helping scientists better understand the nature of Earth’s magnetic fields. Hi-tech imaging technology is enabling researchers to study tiny...

Magnetic vortices defy temperature fluctuations

Magnetic nanovortices in magnetite minerals are reliable witnesses of the earth's history, as revealed by the first high-resolution studies of these structures undertaken by...

The moon thought to play a major role in maintaining Earth’s...

The Earth's magnetic field permanently protects us from the charged particles and radiation that originate in the sun. This shield is produced by the...

Young sun-like star shows a magnetic field was critical for life...

Nearly four billion years ago, life arose on Earth. Life appeared because our planet had a rocky surface, liquid water, and a blanketing atmosphere....

The ancient rotation of the Iberian Peninsula left a magnetic trace

The volcanic rock found in the south of Leon (Spain) experienced a rotation of almost 60º 300 million years ago, an example of what...

Consistency of Earth’s magnetic field history surprises scientists

Earth's magnetic field is generated by the motion of liquid iron in the planet's core. This "geodynamo" occasionally reverses its polarity--the magnetic north and...
